Background: Despite the increasing prevalence of obesity among elderly individuals, there is ongoing debate regarding
the safety of bariatric procedures in this age group.
Objective: This study aimed to assess the efficacy and safety of laparoscopic sleeve gastrectomy (LSG), specifically in
patients aged 55 years and older.
Patients and Methods: A retrospective analysis was performed on patients subjected to LSG in our institution from
2019 to 2023. Forty elderly patients more than or equal to 55 years were included (study group) and were matched with
forty younger patients (control group) based on BMI, sex, and comorbidities distribution. The study compared short-term
outcomes regarding weight loss, comorbidities improvement, operative time, hospital stay, and complications.
Results: There were no significant differences regarding the demographic characteristics or preoperative comorbidities
distribution within the two groups. The mean operative time was slightly longer in the older patients than in the control
group (53.85±12.17 vs. 49.25±16.22 min, respectively), but with no statistical significance. There was no perioperative
mortality in both groups. The percent excess weight loss at 1 year for the older group was significantly lower than that for
the younger group (58.1 vs. 68.74%. respectively). Most comorbidities in both groups were improved or resolved with
no significant statistical. The morbidity rate was 15 and 17.5% for the elderly and the younger group, respectively, with
no significant difference.
Conclusion: LSG is safe and effective in patients more than or equal to 55 years and presents a valuable bariatric option
that is efficient in inducing weight loss and improving obesity-related comorbidities and is associated with an acceptable
morbidity rate comparable to younger populations.
